NIFE Engines, Top Exam Questions and answers, 100% Accurate. Verified. EXPLAIN Bernoulli's Equation, given dynamic pressure, static pressure, and total pressure Bernoulli's equation stats Pt=Pdynamic+Pstatic. As any incompressible fluid passes through a convergent opening its velocity increases and pressure decreases. Describe Airflow in a nozzle When Pressure is decreased and velocity is increased Subsonic: Diverging nozzle=increased pressure, decreased velocity converging...
